Subclaims

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q3 i? Both experimental and control group teachers showed significant reduction in fractions errors from pre-test to post-test, with greater reduction in the experimental group. → Catherine Lewis & Rebecca Perry 2014

q3 · i? · causal · r2

Pre/post assessment of teachers' fraction knowledge in the randomised trial. Table 3 reports maths error means falling from 2.63 to 1.67 in the experimental group (t = 5.113, 72 df, p < 0.001) and from 2.20 to 1.76 in control (t = 2.568, 139 df, p < 0.05); no effect size is printed.

"Both experimental and control group teachers showed significant reduction in fractions errors, with greater reduction in the experimental group."
